Description

modular vacuum cleaner

The present invention relates to a modular cleaner, and more particularly, to a modular cleaner in which each component can be modularized to change the connection order according to usage conditions, or to select and combine only necessary components.

A vacuum cleaner is a device that performs cleaning by sucking or wiping dust or foreign matter in an area to be cleaned.

Such a vacuum cleaner may be divided into a manual cleaner in which a user directly moves the cleaner to perform cleaning, and an automatic cleaner in which the user performs cleaning while driving by themselves.

In addition, the manual cleaner may be classified into a canister-type cleaner, an upright-type cleaner, a handy-type cleaner, a stick-type cleaner, and the like, depending on the shape of the cleaner.

Korean Patent Application Laid-Open No. 2016-0026122 (hereinafter referred to as 'Patent Document 1') discloses a handy type vacuum cleaner. The vacuum cleaner, which is a handy cleaner disclosed in Patent Document 1, includes a suction nozzle, a vacuum cleaning unit, an extension tube assembly, and a handle.

In addition, a suction motor generating a suction force and a dust container are provided in the vacuum cleaning unit, and a handle is connected thereto.

The vacuum cleaner disclosed in Patent Document 1 is a vacuum cleaner having a vacuum cleaning unit provided with a suction motor integrally formed with a handle portion, so that the center of gravity of the cleaner is located at an upper position on the handle side.

As such, the vacuum cleaner having the center of gravity at the upper position is inconvenient in that a large moment load is applied when cleaning the floor, and thus a weight burden is applied to the user.

Accordingly, in Chinese Patent Laid-Open No. 110432820 (hereinafter referred to as 'Patent Document 2') and Korean Patent Publication No. 2020-0098571 (hereinafter referred to as 'Patent Document 3'), a configuration capable of changing the center of gravity of the cleaner is disclosed. there is. That is, it is configured so that the user can change the position of the suction module provided with the motor.

In Patent Document 2, it is configured to separate the suction module and fasten it to the handle located on the upper side or to the side of the cleaner located on the lower side. That is, the user can change and use one of the two centers of gravity, which are the upper and lower center of gravity.

However, when configured as in Patent Document 2, the flow path structure is complicated because the flow path inside must be varied according to the position where it is fastened to the suction module.

And, in Patent Document 3, the suction module is slidingly moved in the longitudinal direction to change the center of gravity to be used. That is, the user can set and use the suction module to a desired center of gravity by fixing it at a desired position while sliding.

However, when configured as in Patent Document 3, the suction flow path must be changed in response to the sliding movement of the suction module, so that the structure of the suction flow path becomes complicated. In addition, since it is necessary to separately configure a rail structure for sliding the suction module, the structure becomes complicated and the weight of the cleaner becomes heavy.

And, Korean Patent Application Laid-Open No. 2018-0076257 (hereinafter referred to as 'Patent Document 4') discloses a modular wireless vacuum cleaner.

The vacuum cleaner of Patent Document 4 divides each part of the cleaner body into an intake module, a collection module, a drive module, and a handle module, and a structure is disclosed in which the specification of each module can be selected and detached and changed according to the user's selection. .

However, in the vacuum cleaner disclosed in Patent Document 4, the center of gravity can be changed by changing the length of the cleaner by adding a dummy module between the drive module and the handle module, but the order of assembly of components other than the dummy module is specified. there is.

Accordingly, in a state in which the additional dummy module is not used, the position of the driving unit module cannot be changed, and thus the center of gravity of the cleaner cannot be changed.

The present invention was devised to solve the above problems, and to provide a modular cleaner that can be used by modulating each component and changing the connection order of each component to variously change the center of gravity of the cleaner has its purpose in

1 to 4 , the modular cleaner 1 according to an embodiment of the present invention includes a main body 20 provided with a driving unit providing suction force and a dust collecting unit for storing dirt, and a handle portion held by the user. (30), a connection part 40 connecting each component and configured to have a hollow so that the sucked air can flow, a cleaning part 10 that contacts the cleaning object and applies a physical force to the cleaning object, and the main body part ( 20) and may include a battery unit 50 for applying power to the driving unit.

In addition, the cleaning part 10, the main body part 20, the handle part 30, and the connection part 40 have a unified portion to be fastened so that all components can be connected to each other. That is, all the components are provided with coupling portions for coupling to each other.

Here, the main body 20 and the connection part 40 are provided with a female fastening part and a male fastening part which are coupling parts on both sides, respectively, so that they can be fastened by changing the order of each other.

And, since the cleaning unit 10 is located at the lowermost end of the modular cleaner 1, only one female fastening part or a male fastening part, which is a coupling part, may be provided.

In addition, since the handle part 30 is located at the uppermost end of the modular cleaner 1, only one male fastening part or a female fastening part which is a coupling part may be provided.

That is, the cleaning unit 10 and the handle unit 30 are located at both ends of the modular cleaner 1, and change the order in which the main body 20 and the connecting unit 40 are connected, so that the main body unit ( 20) can be changed.

The main body 20 is the heaviest configuration in the modular vacuum cleaner 1 because the driving unit 220, the dust collecting unit 230, and the battery unit 50 are provided. The center of gravity of the mold cleaner 1 is changed.

Through this, the user can selectively change the position at which the main body 20 is disposed to change the center of gravity of the modular vacuum cleaner 1 according to the usage environment, thereby improving ease of use.

Accordingly, in the modular cleaner 1 according to the embodiment of the present invention, the center of gravity of the modular cleaner 1 may be changed according to the user's convenience by changing the connection position of the main body 20 .

Hereinafter, a connection relationship between components capable of changing the center of gravity of the modular cleaner 1 according to an embodiment of the present invention will be described in more detail.

The modular cleaner 1 described below includes a cleaning unit 10 , a body unit 20 , a handle unit 30 , a battery unit 50 , and a connection unit 40 . The battery part 50 is fastened to the body part 20 .

The connection part 40 has a hollow for the fluid to move therein, and includes a coupling part for coupling with at least one of the cleaning part 10 , the main body part 20 and the handle part 30 .

And, when the coupling part of the connection part 40 is coupled to the cleaning part 10 or the handle part 30 , the cleaning part 10 or the handle part 30 is connected to the main body through the coupling part of the connection part 40 . It is electrically connected to the part 20 . That is, the connection part 40 is a configuration for electrically connecting other components while mechanically connecting them.

The connection part 40 may be provided as, for example, a first connection part 41 and a second connection part 42 having different lengths. In addition, the length of the second connection part 42 is shorter than that of the first connection part 41 .

Of course, the configuration of the connection part 40 is not limited thereto, and a plurality of connection parts having the same length may be provided, and the connection length may be different by changing the number and order of coupling.

3 and 4 are views showing a state in which the position of the main body 20 is changed and fastened in the modular cleaner 1 according to an embodiment of the present invention.

Referring to (a) of Figure 3, after the first connection part 41 and the second connection part 42 are sequentially connected to the cleaning unit 10, the body part 20 is connected to the second connection part 42, The handle portion 30 may be connected to the body portion 20 .

Here, the order in which the first connection part 41 and the second connection part 42 are connected to each other may be changed.

In this case, the first connection part 41 and the second connection part 42 are used for the purpose of flowing air and for extending the length between the cleaning part 10 and the body part 20 .

The main body 20 is configured to have a larger diameter than other components since the driving unit 220 and the dust collecting unit 230 are disposed therein, and the battery unit 50 is fastened therein.

As such, when the body portion 20 having the largest diameter is located at the uppermost side, it is advantageous for cleaning the gap space.

For example, when cleaning by inserting the cleaning unit 10 into a gap between the floor and the furniture in a space in which furniture such as a bed or sofa is installed, the cleaning unit 10 must be inserted into a deeper space.

In this case, if the body part 20 having a relatively large diameter is disposed close to the cleaning part 10, the cleaning part 10 cannot be put into a deeper space by the body part 20, so that the cleaning space is limited. become narrow

Therefore, since the first connection part 41 and the second connection part 42 having relatively small diameters connect between the cleaning part 10 and the main body part 20, the cleaning part 10 is put into the deepest space to be cleaned. can

And, since the driving unit 220 and the dust collecting unit 230 are disposed therein, and the battery unit 50 is fastened, the main body 20 is the heaviest configuration compared to other components.

As such, the heaviest body portion 20 is located at the uppermost side, and thus has an upper center of gravity.

In the case of using the modular cleaner 1 by connecting to the upper center of gravity, since the center of gravity approaches the user side when the user holds and uses the modular cleaner 1, the feeling of weight in use can be reduced.

For example, when cleaning walls, tables, window frames, ceilings, etc., the user lifts the vacuum cleaner and uses it, so that when the center of gravity is located close to the handle unit 30 side, the user can stably operate the vacuum cleaner. there is.

Referring to (b) of FIG. 3 , after the first connection part 41 is connected to the cleaning part 10 , the body part 20 is connected to the first connection part 41 , and the body part 20 and the handle part (30) may be formed by connecting the second connecting portion (42).

In this case, the first connection part 41 is used for the purpose of air flowing and for extending the length between the cleaning part 10 and the body part 20 , and the second connection part 42 is the body part 20 ) and the handle portion 30 is used for extending the length.

With this configuration, it can be used by connecting the center of gravity to have the upper middle and upper center of gravity moved to the lower side rather than the upper center of gravity described above.

In the case of the upper center of gravity, since the center of gravity is formed close to the handle portion 30 side, the weight is relatively reduced on the cleaning unit 10 side, and thus the cleaning unit 10 side can be easily shaken.

In comparison, in the case of the upper middle and upper center of gravity, since the center of gravity moves to the lower side than the upper center of gravity, the sense of weight is more weighted toward the cleaning unit 10 side, and the moving operation of the cleaning unit 10 side can be more stable. .

And, when cleaning the floor, the moment load applied to the handle unit 30 acts larger than the vacuum cleaner connected to the upper center of gravity in the vacuum cleaner connected to the upper center of gravity, so that the user moves to the upper center of gravity. In the case of using a connected vacuum cleaner, it is necessary to apply more force to hold the handle unit 30 .

Accordingly, when the modular cleaner 1 is connected to the upper middle and upper center of gravity, the cleaner can be operated lighter than the cleaner connected to the upper center of gravity, thereby improving comfort and reducing fatigue.

In addition, when a user lifts and uses the vacuum cleaner when cleaning walls, tables, window frames, ceilings, etc., the user holds the main body 20 with one hand while holding the handle 30 with one hand. cleaning can be done

In this case, since the user holds and operates the main body 20, which is the heaviest component, the cleaner can be operated more stably.

Of course, even in the case of an upper center of gravity, the user can hold the main body 20 with one hand while holding the handle 30 with one hand and perform cleaning.

Referring to (a) of FIG. 4 , after the second connection part 42 is connected to the cleaning part 10 , the body part 20 is connected to the second connection part 42 , and the body part 20 and the handle part (30) may be formed by connecting the first connecting portion (41).

Here, the second connection part 42 is used for the purpose of flowing air and for extending the length between the cleaning part 10 and the body part 20 , and the first connection part 41 is the body part 20 . It is used to extend the length between and the handle portion (30).

With this configuration, it can be used by connecting the center of gravity to have a lower middle and lower center of gravity than the upper middle and upper center of gravity described above.

In this case, since the moment load applied to the handle unit 30 acts smaller than the vacuum cleaner connected by the middle and upper center of gravity, the user uses a smaller force than when using the cleaner connected by the middle and upper center of gravity. The handle portion 30 may be held.

However, since the center of gravity is located close to the cleaning unit 10, in order for the user to rotate the cleaning unit 10 to a desired position by twisting the handle unit 30, more force is required than a cleaner connected to the middle and upper center of gravity. will do

Therefore, the connection between the upper middle and lower center of gravity can be used by connecting the center of gravity to which the user can feel more comfortable according to the user's physical condition and cleaning environment.

Referring to (b) of FIG. 4 , after the main body part 20 is directly connected to the cleaning unit 10 , and the first connecting part 41 and the second connecting part 42 are sequentially connected to the main body part 20 , The handle part 30 may be connected to the second connection part 42 .

In addition, the first connection part 41 and the second connection part 42 are used to extend the length between the body part 20 and the handle part 30 .

With this configuration, it can be used by connecting the lower center of gravity to have the lower center of gravity moved to the lower side rather than the middle and lower center of gravity described above.

In this case, since the moment load applied to the handle unit 30 acts smaller than the vacuum cleaner connected to the middle and lower center of gravity, the user uses a smaller force than when using the cleaner connected to the middle and lower center of gravity. The handle portion 30 may be held.

However, since the center of gravity is located close to the cleaning unit 10, in order for the user to rotate the cleaning unit 10 to a desired position by twisting the handle unit 30, more force than a cleaner connected to the middle and lower center of gravity is required. will be needed

Therefore, the connection between the middle and lower center of gravity and the lower center of gravity can be used by connecting the center of gravity to which the user can feel more comfortable according to the user's physical condition and cleaning environment.

Furthermore, in the case of the lower center of gravity, since more load can be applied to the cleaning unit 10 side, as shown in FIG. 8, the cleaning unit 10 provided with a cleaning mop 190 capable of wiping the floor surface When used, the cleaning effect can be increased.

That is, the cleaning mop 190 rotates and comes into contact with the floor surface, which is the object to be cleaned, and wipes the floor surface. Since it rotates in close contact with the surface, the cleaning performance of wiping the floor can be further improved.

Here, a separate suction port for sucking air is not formed in the cleaning unit 10, and only the cleaning mop 190 is attached to be used only for wiping the object to be cleaned.

Alternatively, the cleaning unit 10 may be provided with a suction port for sucking air and additionally configured to attach the cleaning mop 190 to perform cleaning while sucking in the dirt of the cleaning object while wiping together.

As such, the position of the center of gravity of comfort felt by the user as he operates the vacuum cleaner according to the user's physical condition such as the user's height and arm length and the cleaning environment condition such as the cleaning position and the cleaning type may all appear differently.

Therefore, the user can directly select the center of gravity from which he or she can feel comfortable in operation and assemble each component to further improve the usability.

5 to 8 , the modular cleaner 1 according to the embodiment of the present invention uses a body portion 20 and a handle portion 30, but a cleaning portion 10 and a first connection portion 41 and The second connection part 42 may be selectively connected and used.

That is, the modular vacuum cleaner according to the embodiment of the present invention described with reference to FIGS. 3 and 4 is a cleaning unit 10 , a body unit 20 , a handle unit 30 , a first connection unit 41 , and a second Although it corresponds to an embodiment in which all of the connection parts 42 are used, the embodiment disclosed in FIGS. 5 to 8 corresponds to an embodiment in which some components are connected and used under different conditions of use.

Referring to FIG. 5 , the modular cleaner according to the embodiment of the present invention corresponds to an embodiment using the cleaning unit 10 , the body unit 20 , the handle unit 30 , and the first connection unit 41 .

And, referring to FIG. 6 , the modular cleaner according to the embodiment of the present invention corresponds to an embodiment using the cleaning unit 10 , the body unit 20 , the handle unit 30 , and the second connection unit 42 . .

That is, in the modular cleaner according to the embodiment of the present invention described with reference to FIGS. 3 and 4 , the first connection part 41 or the second connection part 42 is not used. Through this, the length from the handle part 30 to the cleaning part 10 can be configured to be smaller, so that it can be used more suitably according to the user's physical condition or cleaning environment.

Referring to FIG. 5A , after the first connection part 41 is connected to the cleaning part 10 , the body part 20 is connected to the first connection part 41 , and the handle part is connected to the body part 20 . (30) may be connected.

When using the modular cleaner 1 by connecting to the upper center of gravity, since the center of gravity approaches the user side when the user holds and uses the modular cleaner 1, the feeling of weight in use can be reduced.

For example, when cleaning a wall, table, window frame, ceiling, etc., the user lifts the vacuum cleaner and uses it, so that when the center of gravity is located close to the handle unit 30 side, the user can stably operate the vacuum cleaner. there is.

In addition, only the first connection part 41 or the second connection part 42 may be connected and used under conditions in which the use of a shorter cleaner is advantageous, such as in a place where the user is tall or has a low ceiling.

Referring to (b) of FIG. 5 , after the main body part 20 is connected to the cleaning part 10 , the first connection part 41 is connected to the main body part 20 , and the handle part is connected to the first connection part 41 . (30) may be connected.

And, referring to (b) of FIG. 6 , after the main body part 20 is connected to the cleaning part 10 , the second connection part 42 is connected to the main body part 20 , and the second connection part 42 is connected to the second connection part 42 . The handle unit 30 may be connected to each other.

With this configuration, it can be used by connecting the center of gravity to have a lower center of gravity moved to a lower side than the upper center of gravity described above.

In addition, only the first connection part 41 or the second connection part 42 may be connected and used under conditions in which it is advantageous to use a cleaner having a shorter length, such as when the user is short.

In addition, in the case of the lower center of gravity, more load can be applied to the cleaning unit 10 side, so as shown in FIG. 8, the cleaning unit 10 provided with a cleaning mop 190 capable of wiping the floor surface When used, the cleaning effect can be increased.

7 and 8 , the modular cleaner according to the embodiment of the present invention corresponds to an embodiment using the cleaning unit 10 , the body unit 20 , and the handle unit 30 . That is, it is an embodiment in which the length of the cleaner is minimized and used without using the connection part 40 .

Referring to (a) of FIG. 7 , after the main body 20 is connected to the cleaning unit 10 , the handle unit 30 may be connected to the main body 20 to be used.

In this case, the length and weight of the cleaner can be minimized and used.

For example, it is advantageous when cleaning tables, bedding, window frames, and the like.

Of course, when cleaning the bedding, although not shown in the drawing, it may be used by replacing it with a cleaning unit dedicated to the bedding.
